Clare Balding discovers how the birth of broadcasting changed British sport for ever. Radio played a crucial role in the popularisation of sport, suddenly you didn't need to be at the event to know exactly what happened or to be swept up in the excitement of the match. Jean Seaton, the BBC's historian explains how the events that were chosen for outside broadcast began to provide a secular calendar for the year, with the schedule being dominated by the most commentator friendly sports; football and tennis were a fit, flying fishing and pigeon racing were not.

We hear some of the earliest and most celebrated sports broadcasters ; George ' by Jove' Allison, Raymond Baxter, Brian Johnson and John Arlott, who describes the man responsible for the first sports programming on the BBC, Seymour Joly de Lotbiniere.
